CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 511,220, dated December19, 1893.

Application tiled .Iuly 11, 1892. Serial No, 439,614. (No model.)

To all whom t may concern,.-

Be it known that 1, GEQRGE W. SMrLLIE, a citizen of the United States,residing in Newark, Essex county, and State of New Jersey, haveinvent-ed new and useful Improvements in Car-Couplers, of which thefollowing description, taken in connection with the drawings herewithaccompanying, is a specifica tion.

My present invention consists of improvements upon an application'ofmine now pending, hearing Serial No. 43%,558 and filed May ll, 1892, andrelates more particularly to the hook or knuckle operating mechanism,the object of this invention being to provide a cheap and simple deviceor mechanism whereby the hook or knuckle of the coupler may he releasedby its locking device and be drawn or moved to au open or extendedposition immediately upon such releasenient, at one and the sameoperation, by means of a single operating lever through the medium ofconnecting mechanism. This object I accomplish by the means hereinafterset forth in detail and pointed out in the claims.

Referring to the drawings:-Figure l represents the side elevation of acoupler and its operating mechanism, embodying my invention, in positionupon a car with its hook or knuckle in an open or extended position, andFigs. 2 and 3, represent a front and top view respectively, of thesaine.

To explain in detaih-a, represents a portion of a car'hody; b, thedraw-head of the coupler attached to said car-body; b', the hook orknuckle hinged to said draw-head; b2, the locking pin or bolt forlocking said hook or knuckle in a closed position, and c the operatinglever which is supported in suitable bearings c', a', upon the end ofthe car-body a., and is provided with an arm c projecting outwardly fromthe face of the car, which is connected at its free end with the upperend of the locking-pin or bolt b2 through the medium of a connectinglink b3. This operating lever is also provided with an arm or handle c2at or adjacent to its free end as a means for operating the same.

According to my present invention, I make the hook or knuckle h fastwith its pivot-pin h4 in a manner to turn or rotate therewith, by meansof a connecting pin or other suitable means (notshown in thedrawings),the means for connecting said parts not affecting the spirit of myinvention. Said pivot-pin is provided with a cotter-pin or other arm orprojection Zin its lower end at a pointexterior of the draw-head, havingone end projecting laterally therefrom in aline substantially parallelwith the front or engaging end of the hook or knuckle b as shown. Anelbow-lever d is pivoted on the draw-head adjacent to its rear end, andis connected at one end with the projecting end of said cutter-pin orarm b5, through the medium of a connecting rod d', and the opposite endof said elbow-lever (l has connection with an arm c3 of the oper` atinglever c through the medium of a connecting rod d2. By this describedcombination and arrangement of parts, the lockingpin or bolt b2 may beraised or moved from engagement with the hook or knuckle b by means ofits operating lever c, and immediately upon such disengagement, the armc3 of the operating lever c begins to act upon, or raise, the connectingrod d2 and operate the elbow-lever CZ to draw the hook or knuckle b toan open or extended position through the medium of the connections asdescribed.

operating lever c at its point of connection with the rod cl2 in orderto allow the end of the latter to move freely or loosely therein withoutbeing acted upon, until the locking pin has been moved from engagementwith the knuckle, at which time the said arm cS begins to raise the rod(Z2 and operate the connecting parts to draw the hook or knuckle to anopen or extended position as shown. It

is obvious however that the slot at the point of connection between thearm c3 and the rod d2, might be located in the latter in lieu of in theformer as shown, or a link be employed to Ico I secure the desiredaction between the parts as described, without departing from the spiritof my invention.

Another important feature of my invention also consists in the locationof t-he knuckle opening mechanism and in the manner of its connectionwith the hook or knuckle, in a manner whereby it may be applied to anyvertical-plane coupler Without necessitating any change of constructionin the latter, and also in the fact of its being located at the exteriorof the drawhead and independent of the other Working parts of thecoupler; thus obviating the liability of its effecting any of theregular working parts of the coupler, in case of its removal, loss,breakage or other accident, the advantage of which is obvious.

Having thus set forth my invention, what I claim as new, and desire tosecure by Letters. Patent of the United States, is-

1. Iny combination with a car-coupler provided With. a hinged hook orknuckle and a lock-ing pin or device, of an operating lever connectedwith the locking-pin or device throughVV the medium of a linkconnection, andwith the pivot-pin or arm of said knuckle at a pointexterior of the draw-head, through the medium of a pivoted lever andsuitable connections, in a manner to release said hook or knuckle fromits locked position and open the same, substantially as described andfor the purpose set forth.

2 3In combination with a car-coupler provided With a hinged hook orknuckle and a locking pin or device, of an operating lever providedWithan arm having connection with said locking pin or device, and asecond arm having connection With the pivot-pin or arm of said knuckleat a point exterior of the draw-head through the medium of a pivotedelbow lever and connecting means, substan tially as described and forthe purpose set forth.

3. In combination with a car-coupler provided With a hinged hook orknuckle and a locking pin or device, an operating lever provided with anarm having connection with said locking pin or device to operate thesame, of an elbow-lever pivoted on the coupler and connected at itsopposite ends with the Cotter-pin or other projection on kthe pivot-ypin of the knuckle, and With an arm of said operating lever,respectively, through theme- -dium of suitable connecting means,substantially as describedand for the purpose set forth.

Lt. Iny combination with a car-,coupler provided With a hook or knucklehinged thereto, and a locking-pin or device, of an operating leverprovided with an arm havingy connection With the said locking-pinor-device, and a second arm having a loose or sliding connection with aknuckle opening device connecting said second arm and the pivot-.pin orarm of the knuckle, substantially as described and for the purpose setforth.
